I've come across some strange behavior in IE7. Sometimes when an XmlHttpRequest receives a 204 (No Content) HTTP status code on the response, IE sets the XmlHttpRequest object's status property to 1223. In my code, this seems to be happening when my server is returning a 204 from a PUT request - IE seems to be handling the 204 from a DELETE request okay.
Anyhow, jQuery's httpSuccess function is (quite understandably) interpreting the 1223 response as a failure. I tacked on another condition to the end of the if statement: jQuery.browser.msie && r.status == 1223 This seems to fix the problem. However, my overall jQuery knowledge is pretty limited, so I'm not aware of any potential side effects. A quick Google search turns up a few references to this bug on the intertubes, but I can't find anything on MSDN (surprise surprise). Yahoo's toolkit normalizes the 1223 response back to 204: http://developer.yahoo.com/yui/docs/connection.js.html Any chance a fix for this can make it into the next version of jQuery?
